1. Functional characteristics
Structural support: Many building components such as beam supports, column caps, etc. are mainly used to enhance the stability of building structures. Taking steel structure accessories as an example, high-strength bolts can tightly connect steel components, effectively transmit and disperse loads, and ensure the safety of building structures when subjected to external forces such as gravity, wind, and seismic forces. In high-rise buildings, these accessories are crucial for maintaining the vertical load-bearing capacity of the entire building.
Waterproof: Building accessories such as waterproofing membranes and sealing strips are key to ensuring the waterproof function of buildings. Waterproof membrane prevents rainwater and other liquids from penetrating into the interior of buildings through its own impermeability. Sealing strips are used to fill gaps between building components, such as between doors, windows, and walls, to prevent moisture and air from entering and ensure a dry and comfortable indoor environment.
Thermal insulation: Building insulation boards, thermal reflective coatings, and other accessories are important components for achieving building energy efficiency. Thermal insulation board usually has low thermal conductivity, such as polystyrene foam thermal insulation board, which can effectively reduce indoor and outdoor heat transfer. Thermal insulation reflective coatings can reflect solar radiation heat, reduce the cooling energy consumption of buildings in summer, and thus improve the energy utilization efficiency of buildings.
Ventilation: Ventilation louvers, ventilators and other accessories provide good ventilation conditions for buildings. Ventilation louvers are installed on the exterior of buildings or ventilation duct openings, which can prevent rainwater and foreign objects from entering while ensuring air circulation. Natural ventilators can utilize the principles of wind pressure and thermal pressure to exchange indoor and outdoor air, improving indoor air quality.
2. Material characteristics and features
Durability: Most building components require good durability. For example, stainless steel railings, handrails and other accessories, due to their strong corrosion resistance, can be used for a long time under various climatic conditions without rusting. Prefabricated concrete components, such as precast beams, can also play a long-term role in building structures through proper production and maintenance, bearing loads without being easily damaged.
Diverse material selection: There are various types of materials for building accessories, including metals (such as steel and aluminum), inorganic non metals (such as ceramics and glass), organic polymers (such as plastics and rubber), and composite materials. Accessories made of different materials are suitable for different building environments and functional requirements. For example, plastic drainage fittings have the characteristics of light weight and corrosion resistance, and are suitable for indoor drainage systems; Cast iron fittings have higher strength and are more suitable for outdoor water supply and drainage main pipes that can withstand greater pressure.
3. Standardization and customization characteristics
Standardized production: In order to facilitate the interchangeability of building construction and structural components, many building components are produced according to standard specifications. For example, there are strict standards for the size of building bricks, such as the common clay brick size of 240mm × 115mm × 53mm, which ensures the flatness and stability of the wall during masonry. Standard specifications of bolts, nuts, and other hardware accessories can also be easily purchased in the market and assembled with corresponding building equipment and components.
Customized services: At the same time, some special buildings or projects with unique design requirements require customized building accessories. For example, in some architectural restoration projects with historical and cultural characteristics, building accessories may need to be customized according to the style and size of the original building, such as custom-made wooden carved flower boards, ancient style door and window accessories, etc., to restore the historical style of the building.
4. Installation and maintenance characteristics
Installation convenience: Most building accessory designs consider installation convenience. For example, when light steel keel is used for indoor ceilings, simple plug-in or clamping methods are used between its components, and installers can quickly complete the construction of the ceiling. Some new types of building curtain wall pendant systems enable curtain wall panels to be efficiently and accurately installed on the exterior facade of buildings through pre designed installation nodes.
Differences in maintenance requirements: Different building components have different maintenance requirements. For exposed metal accessories, such as aluminum veneer curtain walls, regular surface cleaning is required to prevent dirt accumulation from affecting appearance and performance; For foundation components buried underground, such as steel cages in pile foundations, it is necessary to ensure that their rust prevention measures are appropriate during the construction process, and generally do not require excessive daily maintenance during the service life of the building, unless there are special circumstances such as increased corrosion risk caused by changes in groundwater level.
